The Kids Building Block Ejection Ball Run Toy Set with 3 Changeable Shapes Marble Race Track is a plastic construction set that clicks together into a working ball-run course — then comes apart and rebuilds into a different shape. Each color box holds 500–600 pieces, and the finished run can be launched with the ejection mechanism described in the source. For importers, distributors and private-label buyers, this is a rebuildable marble-run building set rather than a one-shot model: the blocks are the connection mechanism, the track is the build, and the ball launch is the play payoff.
Because the set is block-based, the same carton can serve multiple shelf positions — construction toy, DIY building set, or marble race track — without changing the SKU. The three changeable shapes are the product's core selling point for repeat play: kids assemble, run the balls, then re-form the course. The 28×10×22 cm color box keeps the parcel compact relative to piece count, which matters when you are planning shelf footprint and case pack together.

- Ejection ball-run components for launching balls through the built track
- Color box packaging
The connection mechanism is the part buyers should evaluate first. Blocks click together, so the run is not locked into one configuration — the three changeable shapes are rebuilds of the same piece inventory, not three separate kits. That means one SKU covers a wider age band, and the set stays in play after the first build is finished. The ejection launch adds a mechanical action step on top of the build, giving the track a purpose beyond assembly.
Age range is listed as 0 to 24 months, 2 to 4 years and 5 to 7 years. The upper bands are the natural fit for a 500–600 piece build with small parts and a launch mechanism; the lower band should be treated as a packaging label rather than a play recommendation for a set of this piece count. Confirm your own market's small-parts and age-labelling requirements before listing.

At 48 pieces per carton, the 240-piece MOQ works out to five cartons — a low entry point for testing the SKU before committing to a full container. The 25–35 day lead time gives you a planning window for reorders once the first run sells through. Carton gross weight is 25 kg and net is 23 kg; these are master-carton figures, not the weight of an individual set.
